• O4; A quark pair creation model is introduced to study the XcJ exclusive decays into baryon-antibaryon pairs.The decay widths for processes XcJ → BB- ( J ＝ 0, 2; B = A, ∑0, E-) are evaluated phenomenologicaily with an explicit inclusion of the properties for outgoing baryons described by wave functions in the naive quark model. The results show that states XcJ (J = 0, 2) decay into A pair with a larger branching ratio than into p(p-) pair.
